How Do Clouds Form and Why Do They Look Different?

Clouds are like invisible balloons in the sky, they form when water vapor turns into tiny drops of water or ice. When the air gets cooler, those tiny drops stick together and become visible to us. If there's a lot of moisture, you get big fluffy clouds. If it’s cold enough, you get snowflakes or even thunderstorms.
